ERC-3643 : the T-REX token standard

Hi , Bonjour

ERC-3643 solves transfer eligibility for regulated tokens . the right architecture for compliance at the token level. $32B+ tokenized via T-REX implementations, DTCC integration, SEC citation. The standard works.

Three gaps that become visible when autonomous agents start operating on ERC-3643 tokens at scale:

1. Post-transfer risk context. ERC-3643 validates who can hold a token via ONCHAINID claims. Once an eligible investor holds a tokenized bond, there is no standard interface for an oracle or AI agent to publish a structured, signed assessment of the asset itself / collateral health, issuer exposure, contagion risk. ONCHAINID claim issuers cover identity claims. Asset-level factual attestations need their own interface. On April 18, rsETH collapsed inside Aave . A tokenized asset with a price feed but no continuous assessment of its dependency chain. $6.2B left the protocol in 48 hours.

2. Decision trail for automated actions. When an autonomous agent rebalances a portfolio of ERC-3643 tokens - selling one bond and buying another based on risk signals . there is no standardized way to record why the decision was made. MiCA Article 60 requires audit trails for automated financial decisions. An append-only decision trail interface, composable with ERC-3643’s compliance checks, would close this gap without modifying T-REX.

3. Cross-chain risk propagation. A tokenized fund on chain A holds ERC-3643 tokens representing assets on chain B. If a risk event on chain B affects the underlying asset, there is no standard mechanism to propagate that signal to chain A. The transfer compliance on chain A is intact, but the risk context is stale.

We’ve drafted five interfaces addressing attestation, decision trails, accountability, risk signals, and asset passports — designed to be composable with ERC-3643 without extending or modifying it. The compliance layer handles eligibility; these interfaces handle context.

Has there been discussion in the T-REX community around standardizing the risk/attestation layer that sits alongside the compliance layer, @Joachim-Lebrun ?
